ORGAN.

SPECIFICATION forming part of Letters Patent No. 4%5,044, dated January20, 189;1.

Application filed October 14, 1889. Serial No. 327,039. (No model.)

1'0 aZZ whom it may concern:

Be it known that we, JOSEPH HERBERT CHAsE and JAMEs l TRACY, both ofMeri- .1, in the county of New Haven and State 0 Connecticut, haveinvented a certain new and useful Improvement in Organs, of which thefollowing is a specification.

\Ve will describe parts of an organ embodying our improvement, and thenpoint out the novel features in the claims.

The figure in the accompanying drawing is atransverse vertical sectionof a portion of an organ embodying our improvement.

A designates the reed-board. B designates a number of valvescorresponding to the nu inber of reed cells. These valves are shown asconsisting of strips of wood guided by pins a and faced with anysuitable soft material.

. They are shown as arranged in a chamber or space C, which may be awind-chest combined with any suitable bellows. These valves are raisedto their seats by springs D and are lowered through pins E. The pins, itwill be seen, pass through the reed-board A, and are also guided byfitting in a rail F. These pins extend to the top surface near thecenter of the valves B. The springs D are shown as consisting of wiressecured at one end to a stationary part of the instrument and at theother to the valves in line with the pins E, so as to force them upwardand close them.

G designates one ofa number of levers. These levers will in numbercorresp nd with the pinsEand valves B. They are fulcruined at theforward end to a rail or other support H. At the rear end they extendover the pins E. Pins g, extending from a rail F, guide these levers G.

I designates the keys, of which there will be a number corresponding tothe number of levers G and valves B. These keys are fulcrumed at therear ends to pins t', extending from the key-board J, and are guidednear the forward ends by pins i, extending from the key-board.

K designates adjustable buttons or screws fitted in the levers G andhaving appendages K, which extend beneath the keys. lVhen the keys aredepressed, their corresponding levers G will be depressed. Thus thevalves B will be opened and the corresponding reeds will be caused tospeak.

It will be observed that the key-board is not arranged directly abovethe reed-board, but is considerably forward of the reed-board, and thatthe adjustable buttons or screws K are readily accessible from the frontof the keys beneath the key-board. It will also be observed that thereis a very narrow cheek projection, and that the wind-chest is arrangedbelow and in the rear of the cheek projections. This form of actionwhich we have illustrated allows of the quicker and cleaner opening ofthe valves. Moreover, in it the key-board does not obstruct the freetone of the reeds as much as ordinarily.

\Vhat we claim as our invention, and desire to secure by Letters Patent,is

1. In an organ-action, the combination, with a reed-board, of valves,levers G, pins at the end of said levers extending to the valves neartheir center, springs engaging with the valves in line with the pins,keys above and forward of the valves, and adjusting-screws between thelevers and keys, accessible below the keyboard in front of the valves,substantially as specified.

2. In an organ-action, the combination of the narrow cheek projections,the wind-chest below and in the rear of the cheek projec- 8o tions, thekeys above said check projections, reed-valves below the keys, andconnections between the keys and valves, consisting of levers G, pins E,and buttons orscrews attached to the levers and accessible from thefront below the keys, substantially as specified.
